May be, But what about yamuna river crises ? Heard abt its cleaning project but its always as dirty as it was before, Same in Kolkata..
On theory there are laws and project but how hard they are implemented, Monsoon comes and go and the rivers get dirty again..
If we cannot control and fail to implement rules properly it can back fire on people living near these river routes..
Regarding flood thing i agree..
See, enforcing rules and having infrastructure to enfore rules are two different things. We cannot expect small scale industries to have their own treatment plants. The idea behind treatment infrastructure is to have massive sewage treament facilities in all cities of over 1 million population along major rivers and all industrial areas beyond the threshold of certain revenue.
If you look at industrialization, it always occurs in clusters with related industries around a major hub. This is where central treatment facilities have to come up.
With the Yamuna clean-up, the government has said no one can pump effluents into river. What are they supposed to do? Most medium industries dont have the capital to run their own treatment plants and these systems are only economically viable when scaled to handle huge volumes.
There are about 100 industrial hubs along the stretch of Yamuna and Ganga from Delhi and UP to Calcutta. Setting up 100 treatment plants at a cost of $50 million each is still a $5 billion investment. This would literally eliminate pollution from the two most important waterways of our country. Bramhaputra does not require anything as of now as NE is not industrialized.
Similarly, another $5 billion investment into urban sewage systems along these river systems would cover all population areas of over 1 million people.
It can be done if we have the will and the vision to do it. But alas...
